Hair loss in humans from toxic cancer radiotherapy and chemo-therapy might be minimised if these treatments are given late in the day, scientists including an Indian-origin researcher, have found.
Researchers found that mouse hair has a circadian clock — a 24-hour cycle of growth followed by restorative repair. In the study, mice lost 85 per cent of their hair if they received radiation therapy in the morning, compared to a 17 per cent loss when treatment occurred in the evening. The scientists from the Salk Institute for Biological Studies, the University of Southern California and the University of California, Irvine, worked out the precise timing of the hair circadian clock, and also uncovered the biology behind the clockwork the molecules.

Pigeon bolt SETS a record at £310,000
Brussels: Lightning fast pigeon Bolt, with a name and pedigree to match, has become the world’s most expensive racing bird with his Belgian breeder selling it for £310,000 ($400,000) to a Chinese businessman.
Belgian-bred pigeons have a worldwide reputation for being the fastest around, yet the record prize surprised anyone involved in the sport, auction house Pipa said.
Pipa CEO Nikolaas Gyselbrecht said that on Tuesday he was “stunned by the prices offered” in the auction of 530 birds which also yielded a world record of £4.345 million($5.58 million).
Nine of the 10 top birds went to China or Taiwan.
The previous record for a sale of a single bird stood at £250,000 ($322,000). Top birds after sale are traditionally used for breeding only.
